Is this Chlorosis?
A couple of pictures of two roses in the back bed. Last year these were small but very happy, healthy green and bloomy. They were actually greener a few weeks ago then they are now. I've noticed especially in the past two weeks that the leaves on most of one one plant and part of another (they're the same and unnamed) have suddenly turned a rather icky yellowish color. I've never seen this on my roses before. I know what over watering looks like out there and this isn't it. I would greatly appreciate any thoughts on the matter. Thank you.
By the by both of these guys have and have had RMV forever. I trim off the really affected parts and they normally shine on despite that fact.
